As far as I know the diagrams are B&W
Why did you have to buy JetBook Color then?
You did not say anything about he clarity of the diagrams.
Are they shown much clearer considering the bigger size of the screen?

tks

Hi PF4Mobile, Thanks for your input.

Whether the schematics are colour or not depends on the source, however, my interest was to view aircraft schematics printed to Adobe Acrobat Printer. I was hoping to easily zoom and pan using the pen, which turned out to have to be done by using the buttons and menu selection (time consuming). I could read the values only at full zoom but this depends on the size and quality of the original schematic I guess. I wanted to carry the Jetbook with me around the aircraft instead of heavy manuals or sheets of paper, make annotations etc. A finger sensitive touch screen, allowing pan and zoom would have been amazing but only pen input was acceptable. Unfortunately this doesn't work as expected.

I hope that someone develops firmware for the Jetbook Colour, similar to the firmware available for the Sony PRS 950. Then we won't have to depend on the manufacturer. It's not perfect but every iteration improves on the original and is fully uninstallable.

Hi Angelo,
Thanks for your enquiry.
The jetBook Color has the WiFi chip built-in and needs to be activated by a browser. This should be released in the next update on March 1st or April 1st the latest.
It should also link you to publishers, bookstores, and more.
Hope I helped, and if you need anything else just let me know.

Best Regards,
Greg Stetson

Hi Mike,

Thank you for your email.

We are working on the JetBook Color updates so the browser should be updated
either on 03/01/12 or 04/01/12.

E-ink technology isn't really optimized for fluid motion. Therefor zooming and panning aren't going as well as they could on an LCD screen.

So, a few days ago, appeared on the forums Mobileread fairly complete and articulated a review of the device by a user who has purchased and that we now we’re going to summarize, in order to obtain some general guidelines.

Most baby boomers wearing glasses have it from reading books. Most x-generation have it from computer and TV screens with too high bright settings and radiation levels.
LCD does not radiate 'dangerous' (for the eye) radiation like a CRT.
Most late 80's and later CRT's have a filter to filter out this radiation.
Modern LCD's that are based on LED lights, have even less an issue with radiation.

surprisingly, there hasn't been solid evidence that reading books causes eye problems. evidence points to our eyes (born not perfectly round), but children / teenagers etc have the eye-power/strength to focus and ignore the error... as they age, they lose this eye-power/strength to focus, and get hyperopia/myopia

This is the same firmware as ours, just in Russian. Probably most of us have the Eng-Span version, this is just the corresponding Eng-Rus one.

Btw. In bright sun light the colors become almost not washed out .
Very good light conditions are a prerequisite for a good experience on this device, maybe that's also a good thing, it reminds you that your eyes also need very good light conditions for prolonged reading sessions.

i assume this is because of how color eINK is made (color filters over the individual pixel... need good light to go through the filter, lose some magnitude from the filter absorbing some of the energy, bounce back out to reach your eyes)

when I get one, I'll try to post a HD video of it in bright sunlight vs my kindle DX G (and my friend's ipad2 if I manage to borrow it)

The fabrication method seems to leave a small gap around the edge of each colour filter to let more light in but it's still a lower contrast technology than the equivalent black and white eInk pearl screen. See the attachment to this post for a picture of the filters: http://www.mobileread.com/forums/sho...1&postcount=20

I've also found that the more light there is on the screen the more uniform and white the background looks (ie all the pixels with RGB filters in front of them that are set on white). In dull conditions the filtered pixels are quite prominent in a checker board pattern - as shown in the attachment here: http://www.mobileread.com/forums/sho...2&postcount=13
